BACKGROUND OF THE DISCLOSURE

1. Field

The present disclosure relates to a decoration tile used as a finishing material on an indoor floor of a building or an apartment house, and more particularly to decoration tiles, each decoration tile installed by coupling, wherein coupling grooves are formed at a widthwise side and at a lengthwise marginal side of a rectangular decoration tile, and coupling lugs are formed at the other opposite widthwise side and the other opposite lengthwise marginal side of the rectangular deco tile, such that a plurality of decoration tiles can be mutually coupled and installed on an indoor floor surface, whereby a plurality of decoration tiles can be insertedly installed by allowing the coupling lugs to be inserted into the coupling grooves, and allowing the rugged lugs to be tightly and securely inserted into the rugged grooves, to increase coupling force between the tiles, to prevent the tiles from being discrete and disengaged, and to simplify construction work, and whereby no adhesive harmful to human is used due to a plurality of tiles being tightly coupled to provide no harm to dwellers.

2. Background

Generally, an inner floor of building or an apartment house is used with such finishing materials as decoration tiles or woods. However, woods as raw materials for finishing materials of buildings and apartment houses are widely employed of late, in consideration of environment-friendliness and aesthetic values.

Flooring materials for indoor floor may be classified into woods, decoration tiles and laminated paper (or plastic), where the wood floor is used with raw wood itself or processed plywood itself.

The wood floor is advantageous in that texture of natural wood is beautiful, and excellent in terms of indoor humidity control, and any deformation of woods can be restored to a normal shape, once appropriate humidity and temperature are provided and maintained. However, there are many disadvantages in that the wood floor is weak to fungus and/or bacteria propagation, easily scratched, and used with an adhesive, and installation cost is very expensive, and noise is generated when dismantled and expenses thereto are high.

The decoration tiles are widely used as flooring materials in a house or an office, because they are inexpensive and scratch-resistant, although the decoration tiles are made with PVC materials printed with various patterns to embody floor textures. The decoration tiles are formed in various patterns by being provided with natural marble, natural wood and carpet-like textures to allow the patterns to have interior decoration effects.

Each of the flooring materials thus mentioned are manufactured in a predetermined size, and attached to indoor floors using adhesives. The problem is that the flooring materials are attached to the indoor floors using the adhesives, which in turn produce harmful substances causing skin diseases and/or respiratory diseases to the disadvantage of dwellers.

In order to solve the aforementioned problems, in prior art as illustrated in FIG. 1, one distal end of wood floor or a deco tile is formed with a coupling lug (100), and the other opposite distal end is formed with a coupling groove (200) to allow the coupling lug (100) to be inserted into the coupling groove (200), whereby many wood floors or deco tiles are mutually coupled to form an indoor floor surface to reduce an amount of adhesives and to enhance workability.

However, the coupling method according to the prior art is disadvantageous in that coupling power between wood floors or deco tiles decreases to cause the wood floors or deco tiles to become discrete or disengaged, and the wood floors or deco tiles become dislodged due to insecure coupling if the wood floors or deco tiles are disengaged or separated from a floor surface.

That is, the wood floors or deco tiles are insecurely laid on the floor surface just by being inserted from one wood floor or deco tile to the other wood floor or deco tile, to decrease a mutual coupling power, resulting in occurrence of the wood floors or deco tiles being separated or disengaged, and occurrence of noise and dislodgement of wood floors or deco tiles if part of the wood floors or deco tiles is fallen apart, leading to improper poor construction works.

SUMMARY OF THE DISCLOSURE

An object of the present disclosure is to solve at least one or more of the above problems and/or disadvantages in whole or in part, in which mutual coupling power in conventional deco tiles decreases after the tiles are laid on a floor surface to result in occurrence of the tiles being discrete or disengaged, and occurrence of noise and dislodgement if part of the tiles is fallen apart, leading to improper poor construction works and hazard to dweller health, and to provide an easily press-fitted, installable and unharmful decoration tiles, excellent in coupling force among decoration tiles through mutually press-fitted plurality of decoration tiles, capable of preventing the decoration tiles from being distanced and disengaged and free from adhesive harmful to human body.

In order to achieve at least the above object, in whole or in part, and in accordance with the purposes of the invention, as embodied and broadly described, and in one general aspect of the present invention, there is provided a press-fitted decoration tile that is employed in construction work on an indoor floor surface, the tile comprising: a groove unit formed at each one lengthwise marginal circumference and one cross-wise marginal circumference of the rectangular decoration tile; and a lug unit formed at each other lengthwise marginal circumference and other cross-wise marginal circumference of the rectangular decoration tile that face the each one lengthwise marginal circumference and one cross-wise marginal circumference of the rectangular decoration tile.

Preferably, the groove unit includes a lug formed at a distal end of an external side of the decoration tile and a coupling groove formed at an inner side, wherein the lug is formed from a floor surface of the decoration tile at the distal end of an external side with a height lower than a thickness of the decoration tile, and the coupling groove is slantly formed on an upper surface of the decoration tile with a height lower than that of an upper end of the lug.

Preferably, the lug unit includes a coupling lug formed at a distal end of an external side of the decoration tile and a groove formed at an inner side, wherein the coupling lug is formed at the distal end of an external side of the decoration tile from an upper surface of the decoration tile at a height lower than a thickness of the decoration tile, and the groove is formed on the floor surface of the decoration tile with a height higher than that of a bottom end of the coupling lug.

There is an advantageous effect in the press-fitted decoration tile according to the present disclosure in that a plurality of decoration tiles is coupled and installed on an indoor floor surface by forming a groove unit at each one lengthwise marginal circumference and one cross-wise marginal circumference of the rectangular decoration tile, and a lug unit at each other lengthwise marginal circumference and other cross-wise marginal circumference of the rectangular decoration tile that face the each one lengthwise marginal circumference and one cross-wise marginal circumference of the rectangular decoration tile, whereby the plurality of decoration tiles is press-fitted thereamong on the indoor floor surface to make the coupling force among the decoration tiles and to prevent the decoration tiles from being distanced and disengaged.

There is another advantage is that the press-fitted decoration tile according to the present disclosure is easily installable, excellent in coupling force among decoration tiles through mutually press-fitted plurality of decoration tiles, and capable of dispensing with use of adhesives and freeing dwellers from being worried about hazards.

There is still another advantageous effect in that the decoration tiles are press-fitted crosswise and lengthwise to provide an excellence in coupling force of decoration tiles, and no adhesive harmful to human is used to enable a tightly secured installation of the decoration tiles on an indoor floor surface, whereby there is no harm to human and no poor construction is allowed with excellent durability after installation.

There is still further advantageous effect in that the existing wooden floor can be replaced by the decoration tiles according to the present disclosure, no adhesive is used to satisfy consumer needs of environment-friendliness and to allow consumers instead of skilled workers to personally install the decoration tiles as a DIY (Do It Yourself) product, and to satisfy the requirement by world markets.
